We read with interest the article titled “Selective Laser Trabeculoplasty as Primary Treatment for Open-Angle Glaucoma” by Melamed et al.1 We congratulate the authors for providing substantive evidence on the efficacy and safety of selective laser trabeculoplasty (SLT). We would like to point out, however, that this evidence regards only the first 3 postoperative months, since an increasing number of patients were lost to follow-up thereafter (Figure 2). Although the authors report a mean postoperative follow-up period of 11 months, this is slightly misleading, as only 38% of the treated eyes (17/45) were observed for 12 months.
